BLS 451's

The 451's should be way more than enough. What you may need to do is move them up to 6 volts. Mine picked alot once I did this. With the flybarless speed is the important thing in a servo with torque comming in at a close second. Servos in the 100 oz range or above have plenty of the push needed to do the job. Remember, ccpm helis use more than one servo to do the job, so depending on the movement you will have 2 or 3 servos working together.

My 2 cents

I finally figured it out and now have a helicopter flying just the way that I like. Some Zeal vibration absorbing material was the secret to success. I have used this before on tail gyros and it always works wonders. For those who don’t know about it’s a high-density gel type material that is incredibly good at isolating vibration. It’s a little expensive but well worth the price. http://www.heliproz.com/prodinfo.asp?number=138006

Now I can run much higher gains with no oscillations. With more gain high-speed pirouettes are rock solid. The secret to good pirouettes with the SK360 is lots of hiller and damping gain. Just keep cranking it up until it gets unstable then back off a little.

I also did some experimenting with dampers and found that harder is not always best and I could actually run more gain if the dampers were not too hard. Since the gyro is controlling the cyclic rate and feel, harder dampers don’t change the way the helicopter performs in flight that much it just effects the amount of gain that you can run. Optimum damping will be different for each setup and headspeed so that’s something everyone should experiment with.

So BTS,

What did you end up with for your Hiller gains?

Gains with the dials disabled. I found it easier to fine tune things that way but you have to have a computer available.

Hiller (E, A): 60, 55
Damping: 24, 20

Is anyone else running the SK360 with gains that high?
